推荐答案
尝试略微更改保存方式:
Try changing the way you save it slightly:
FileUpload1.SaveAs(Server.MapPath(filePath) + fileName);成为:
FileUpload1.SaveAs(Server.MapPath(filePath + fileName));原因是MapPath不会在路径规范中添加尾随的``/''字符-因此您的文件会尝试保存到
The reason is that MapPath does not put a trailing ''/'' character on the path spec - so your file would be trying to save to
C:\mywebsite\fileupmypdffile.pdf
